DUMB-BELL.

QPECIPICATION forming part of Letters Patent No. 318,078, dated May 19, 1885.

Application filed December 22, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GILBERT L. BAILEY, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented a new and useful Improvement in Dumb-Bells, of which the following is a specification.

My invention relates to improvements in the form and construction of dumb-bells for exercising the muscles, and has for its objects to make them more desirable to handle, symmetrical in form, and of greater strength than those now in use. These objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 is a view in elevation of a dumb bell complete; and Fig. 2, a longitudinal sectional View of a dumbbell, showing the form of construction of the several parts and the manner of putting the whole together.

Similar letters refer to similar parts throughout the several views.

My invention consists in two separate semispherical cast-iron heads, A A, each having a hole through its center and a handle, H, of wood or other non-metallic substance, to the ends of which the heads are bolted. Each head has afiat-bottomed countersink on its opposite sides. That on the inner side is shallow, and of the same diameter as the ends of the handle which it receives.

is bored lengthwise and is about four inches The handle H l in length. -A Wrought-iron bolt, B, having a head on one end and a screw-thread on the other, carrying a nut, N,is passed through both 1 heads, and also through the handle, and the three pieces are fastened to each other with the handle intermediate the heads by means of the screw-nut. The countersink d in the outer side of the head is deep enough to admit the nut and bolt-head below its surface. The ends of handle H are formed to fit the in side countersink, c, and is thereby prevented from splitting or being moved out of its place.

The advantages of this dumb-bell over those in common use are, that the heads can be made more comely in appearance. The handle, being non-metallic, is more agreeable in use, and

does not require to be covered to make it
